Strong together: Both a gold complex and a palladium complex are needed as catalysts in a Stille‐type reaction that does not require an organic halide for the oxidative‐addition step (see scheme; dba= trans , trans ‐dibenzylideneacetone). The bimetallic catalyst system facilitates the construction of highly substituted olefins. Additional examples of reactions that employ the combined action of a π acid and a cocatalyst are briefly discussed.
